Airships past and present, together with chapters on the use of balloons in connection with meteorology, photography and the carrier pigeon . s been madehas been largely due to the fact that there has been littledifficulty in raising funds, and successful experiments have beencarried out by Botch,Marvin, Eergusson, Clayton, Eddy, and the modern point of view there are three main forms ofkite ; firstly, the Malay kite, as improved by Eddy; secondly,the Hargrave kite, which appears in all sorts of shapes ; and KITES. 119 thirdly, the keel-kite, invented by Clayton. The first two typesare fairly well known, but the keel-kite is not in the sameposition, and therefore requires to be more fully described. Aframework, built up out of wood and phosphor bronze wire, iscovered by cambric and used as a keel. It is mounted on apiece of pine wood, and the rest of the kite is constructed mthe usual way. The only difference lies in the possibilityof slightly altering the angle of inclination of the sails. Bymeans of a spring, it is possible to lessen the inclinationof the exposed surfaces to the wind, so that it flies along more. Fig. 72.—Codys kite. easily under a diminished pressure. This is a real improve-ment. On the one hand, the vertical position of the kite ismore stable, and on the other, a serious accident is renderedmore improbable. In mounting to great heights it is necessary to use a lightkite. In consequence, it is not likely to be very strong. It hasoften happened that a kite of this kind has been destroyed bythe wind, which may be blowing strongly at a great height with-out being very noticeable at the ground level. This is a commonoccurrence in meterological work. As it is not possible to reachgreat heights with one kite, it is usual to put several on the samecord, one behind the other, and sometimes as many as nine are 120 AIRSHIPS PAST AND PRESENT. joined together in this way. A kite of this kind is quite able tosupport the weight of the rope and reco
